Since the mid-1990s something remarkable has been happening. Crime has been falling for two decades. More remarkably hardly anyone predicted this development, and it has continued despite the recent recession and cuts to police budgets.
And this surprising trend is not confined to the United Kingdom, but seems to be replicated throughout the developed world.
In The Crime Conundrum, Dominic Casciani attempts to explain this extraordinary phenomenon, talking to experts and policy makers. Have we misunderstood the causes of crime and the role of government policies, the prisons and the police?
Producer: Adam Bowen.
Casciani asks whether the decline of crime is because of - or despite - the policies of successive governments of left and right.
